ing' carried in bushings 20 pressed in downwardly extending bosses 21 formed in the 'main engine housing 22, and deriving its mo- -'tion from the main crank-shaft through the Imedium of suitable gearing (not shown).

In opera-tion, as the shaft 19 revolves by reason of its geared connection with the main shaft (inthis case,`at half engine speed), the sleeve valve is lifted and oscillated, and then lowered and again oscillated, the two oscillatory movements, however, being unlike; that is to say, as the valve rises the oscillation is such as to bring the valveport inv one part ofthe cylinder and as the valve lowers the oscillation is such as to bring the valve port in another part of the cylinder. By proper positioning of the ports in the valve itself, and inthe walls of the cylinder, the events of the cycle kare carriedout. Referring to Fig. 3, the sleeve valve crank 18 is shown at about the mid-point in the vertical stroke of the parts connected therewith, while at theysame time the partsV are at an extremity of the arc of oscillation about their respective center lines. As the sleeve shaft 19 is revQlved in the direction of the arrow thereon, the crank-pin 18 for an individual valve will f assume successively Y higher positions, carrying Lthe entire mechanism upwardly and at the same time turning the valve about its axis'C. The related direction of movements p are shown by small arrows ontheparts themselves, and continued rotation v,brings the parts tothe position as shown in` Figs. 1, 2 and 5, wherein the crank-pin 18 has lreached the upper dead center, thevalve 1 istat the i rclescribed, a cylinder, a sleeve valve 1n said point of its uppermost travel, and at the center of the arc of its oscillation. Y In Fig. 4, the shaft 19 has marde one half turn as compared to Fig. 3, bringing the valve 1 again to substantially the same point as in Figv, but at the other extremity of its are of oscillation about its center C.

A`moditication of the `invention is shown in Figs. 6 andv 7 in which the guide member 9 has, at its lower end, a transversely extending boss 24 into which the shank 25 of a connecting rod 26 is slidably fitted. At the lower end of the valve 1 are integral bosses 4', 4', each having a transverse slot 5', while inthe .end of the connecting roda pin 27 is litted. and retained by a Cotter 28, this pin being journaled in the boss 4.

A further modiiication is shown'in Figs. 8 and 9 in which the boss 4 at the vlower end of the valve 1 has atransverse slot 5; a spherical seat. machined in the boss receives a ball 29 which is slidably engaged with the trunnion pin 10; a vsocket member 30 completing the seat is pressed into the opening 31. i

vBy V this construction it will be seen that I am enabled to provide a valve-actuating `mechanism withfew moving parts, 'and one in which the yoperating shaft isrotated at half engine speed, with a consequentreducduction in Wear andadvantagein adjustments to take up for wear.

Thls arrangement also enables me to arrange all of the valve operating mechanism at one side of the engine, with the valve sleeve bosses projecting laterally, which enables me to use the conventional crank-case construction with a strengthening rib between each cylinder and also cylinder bores.
